ABSTRACT OF THE DISCLOSURE The stenographic apparatus disclosed hereinemploys a plurality of punches which are independently operable onrespective drive means to punch distinctive patterns of holes in a papertape. Each of the punches is controlled by a respective key of astenographic machine. Thus, when a preselected combination of keys areoperated, the corresponding punches are operated to punch theirrespective patterns in a predetermined section of the tape. Theapparatus also includes means for advancing the tape to place a new,unpunched section of tape in position to be operated on by the puncheswhen previously operated keys are released. In this way, the apparatusprovides a punched record which is readable for digital computingequipment for automatically preparing a printed transcription of therecord.

This invention relates to stenographic apparatus, and more particularlyto such apparatus providing a punchtape record which is readable bydigital computing equipment for automatically preparing a printedtranscription of the subject matter being recorded.

In the preparation of official records of court proceedings and thelike, the initial record is taken down manually either in shorthand orwith the use of a stenographic machine. While stenographic machines havean advantage over the use of shorthand in that they facilitate thepreparation of a transcription by other than the original machineoperator, both methods as now practiced do require that the initialrecord be transcribed by a human agent.

Among the several objects of the present invention may be noted theprovision of stenographic apparatus which will provide a punch-taperecord readable by digital computing equipment for automaticallypreparing a printed transcription of the subject matter being recorded;the provision of such apparatus which is usable with a stenographicmachine of the type having a plurality of keys which are manuallyoperated in predetermined combinations to make a printed record suitablefor later transcription; the provision of such apparatus in which theoperation of each of the keys produces a predetermined pattern ofperforations in the tape according to a preselected code, each patternbeing distinct from the patterns made by any of the other punches; theprovision of such apparatus by means of which a record corresponding tothe operation of a plurality of said keys in predetermined combinationmay be prepared simultaneously with that operation; the provision ofsuch apparatus which will operate rapidly; the provision of suchapparatus which is portable. relatively simple and inexpensive; and theprovision of such apparatus which is reliable. Other objects will be inpart apparent and in part pointed out hereinafter.

Briefly, apparatus according to the present invention is usable with astenographic machine of the type having a plurality of keys which aremanually operated in pre determined combinations to make a printedrecord suitable for later transcription. The apparatus includes aplurality of punches which are arranged to operate independently on asection of record material aligned by suitable guide means. Each of thepunches is operative when actuated to punch a predetermined pattern ofperforations in the record material, which pattern is distinct from thepatterns made by any of the other punches. The patterns representrespective ones of the keys according to a preselected code. Arespective separate drive means is provided for each of the punches andis operative when tripped for actuating the respective punch. Theapparatus includes also means responsive to the operation of each of thestenographic machine keys for tripping a respective drive means andmeans responsive to the release of previously operated keys foradvancing the record material to place a new, unpunched section of tapein position to be operated on by the punches. Accordingly, operation ofthe stenographic machine produces a coded punch-tape suitable forautomatic transcription of the subject matter being recorded.

The invention accordingly comprises the constructions hereinafterdescribed, the scope of the invention being indicated in the followingclaims.

In the accompanying drawings in which one of various possibleembodiments of the invention are illustrated,

FIG. 1 is a flow chart representing the transformation of information inthe automatic preparation of a transcription using apparatus accordingto the present 1nvention;

FIG. 2 is an end view of apparatus for punching paper tape inpredetermined patterns;

FIG. 3 is a section on the line 3-3 of FIG. 2 showing the arrangement ofpunch pins therein;

FIGS. 4 and 5 are top and side views, respectively, of apparatus forfeeding paper tape through the punch of FIG. 2;

FIG. 6 is a schematic diagram of a control circuit for the punch andfeed apparatus of FIGS. 25; and

FIG. 7 is a diagram illustrating the patterns of perforations producedin successive portions of a tape to represent various portions of therecord in relation to respective lines of the corresponding printedrecord made by a typical stenographic machine.

Corresponding reference characters indicate corresponding partsthroughout the several views of the drawings.

Referring now to FIG. 1 there is indicated at 11 an essentiallyconventional stenographic machine of the type having a plurality of keyswhich may be manually operated in predetermined combinations to producea printed record suitable for later transcription by the operator orsome other person knowing the code format used in operating the machine.The printed record as indicated at 13 typically comprises a paper tape.Each separate operation of the stenographic machine prints a line orhorizontal row of characters on the tape, there being one character inthe line for each key used in the operation. the characters beingdistinct from each other. When the keys are released, the tape 13 isadvanced so that the next operation of a group of keys prints itscharacters in a new line on the tape. Certain of the stenographicmachine keys may also be caused to print a second character, alsodistinct from all the other characters, by the operation of a shift keywhich shifts the type faces with respect to the printing platen.

At 15 is indicated a paper tape punching apparatus according to thepresent invention which is electrically coupled to the stenographicmachine 11 to be controlled thereby. When the stenographic machine 11 isoperated, punch 15 produces a punched paper tape record as indicated at17. One section of the punch-tape represents each line of the printedrecord, the different printed characters being represented byrespective, distinctive patterns of perforations within the section.Each section of tape includes a position for a row of perforations foreach of the possible characters. The pattern of perforations produced inthat row when the respective key is operated is preferably aconventional digital representation of that character in a preselectedconventional code as typically used in digital computing equipment.

The punched tape record 17 is fed into a translating digital computer orcompiler 19 having a memory in which are stored the English wordscorresponding to the predetermined combinations of keys which theoriginal operator employs to designate those words. Each such Englishword is stored in the memory at an address, the designation of which isthe digitally coded equivalent of the letters which represent that wordin the stenographic language being used. Since the punched tape recordis already in digital encoded form, the translating computer 19 thusmerely performs a relatively straight-forward retrieval program toobtain the English word equivalent of the punch-tape record. Havingobtained the English word equivalent, the completed transcription mayeither be printed out directly as indicated at 21 or stored on paper ormagnetic tape for later printing. This latter procedure is preferable inthat it saves computer time, computer operation typically being manytimes faster than the operation of available printers.

Having thus explained the general mode of operation of this apparatus,the function of the specific construction shown in FIGS. 2-5 may readilybe understood. In FIG. 2 there is shown at 24 punching apparatus whichincludes a plurality of independently operable punches. The actualperforating of the paper tape is performed by a multiplicity of punchpins 25 cooperating with a die 27 having a corresponding multiplicity ofopenings suitably positioned therein (see FIG. 3). A row of such holesin an appropriate pattern is provided for each of the keys of thestenographic machine and sufficient holes are provided in each of therows so that the digital code representation of each of the lettersprinted by the stenographic machine may be punched into a single sectionof paper tape. The perforations representing a single printed characteron the printed tape 13 all lie in a row extending across die 27. The rowis also transverse to the length of the paper tape being punched as Willbe apparent hereinafter. The pins 25 are maintained in alignment withthe holes in die 27 by a. guide block 31 having a similar multiplicityof holes therein. Guide block 31 and die 27 are separated by suitableshims or spacers 33 which define a passage 34 for paper tape between theguide 31 and the die 27.

The punch pins 25 are driven, in predetermined combinations, throughguide block 31 and into die 27 by a plurality of solenoids S1 which aremounted on a common base 35 with die 27. Solenoids S1 are of the pushtype and include plungers 36 which are coupled to the respective sets ofpunch pins 25 by means of respective levers 37. The levers 37 arepivoted on shafts 39 which are in turn journaled in frames 41 mounted onbase 35. The pins 25 are driven by direct contact with the respectivelevers 35 and are loosely coupled to the levers by links 43 forretraction.

For each group of punch pins 25 representing one of the letters printedby stenographic machine 11, there is at least one solenoid S1 so thateach such group of punch pins may be operated independently of the othergroups. In certain cases it may be necessary that the pins representinga given character be operated by more than one solenoid since thetypographic machine 11 may print a second character in any one column ifthe shift control is used. The use of more than one solenoid to effectpunching of a given pattern of perforations in the paper tape does not,however, effect the ability to punch each such pattern independently ofthe other patterns which may be punched in a given section of tape. Forease in description, the group of components employed to punch a givenpattern of perforations representing one of the keys of the stenographicmachine is hereinafter and in the claims referred to as a single puncheven though two or more separate such mechanisms are in fact illustratedand employed since such several mechanisms may be operated together tofunction as a single unit when suitably controlled.

Referring now to FIGS. 3 and 4, the paper tape is drawn through thepunch by a capstan 45 which is driven intermittently, as describedhereinafter, to advance the tape section by section. The tape is held inengagement with capstan 45 by a pressure roller 47 which is urgedagainst the capstan 45 by springs 49. The motive force for capstan 45 isprovided by a fractional horsepower electric motor 51 which is allowedto run continuously during operation of the apparatus. The shaft ofmotor 51 is coupled to capstan 45 through a flexible coupling 53 and aclutch and brake coupling 55. Coupling 55 is electromagneticallyactuated and is of the conventional friction type which couples theoutput shaft to the input shaft when the coupling is energized andbrakes the output shaft when the coupling is deenergized. Such couplingsare fast-acting and can both start and stop capstan 45 within a fewdegrees of rotation of the shaft of motor 51.

After being pulled through the punch, the paper tape passes over idlerrollers 57 and 59 and is wound-up on a pickup reel 61 which is rotatedby appropriate means (not shown).

Referring now to FIG. 6, electric power for energizing this apparatus isobtained from a suitable source or supply mains through a pair of leadsL1 and L2. Motor 51 is connected directly across leads L1 and L2 as isthe primary winding W1 of a transformer T1. Transformer T1 includes asecondary winding W2 having a centertap CT. The out-of-phase A.C.provided at the opposite ends of Winding W2 is full-wave rectified by apair of diodes D1 and D2 and is filtered by resistor R1 and a capacitorC1 in conventional manner to provide a source of DC. across a pair ofterminals 63 and 65. Capacitor C1 is shunted by a conventional bleedresistor R2. Positive current is supplied to the apparatus through asupply lead L3 which is connected to the terminal 65 through an on-offswitch SW1. A supply lead L4 is connected directly t0 the negativeterminal 63 and is grounded as indicated at 66.

In FIG. 6 there is indicated a solenoid S1 for each punch pin positionalthough it will be understood that, as illustrated in FIG. 2, severalof the punch pins may in fact be operated by a single solenoid dependingupon the particular mechanical arrangement used. The solenoids which areenergized together to provide a single given pattern are indicated asbeing wired in series although, as will be understood by those skilledin the art, parallel Wiring may also be used by suitably adjusting theelectrical parameters of the circuit. Certain of the punch pin positionsare utilized for both of the two possible printed characters which maybe printed by each key. Such dual operation may be accomplished by providing a dual winding on the respective solenoid, as indicated in FIG. 6by leads extending to both sides of certain of the solenoids, or bysuitable electronic gating (not shown).

Energy for operating the solenoids S1 is stored in suitable capacitorsC2, there being one capacitor C2 for each row of punch pins. Thecapacitors are charged from DC. supply lines L3 and L4 through thenormally closed contacts of respective D.P.D.T. switches SW2. SwitchesSW2 are mounted on the stenographic machine 11 and are operated inresponse to the operation of respective ones of the machine keys. Wheneach switch is operated, the respective capacitor C2 is discharged intoselected ones of the solenoids S1 as described hereinafter.

The operating winding W3 of a multicontact relay RY1 is connected acrossD.C. supply lines L3 and L4 by means of a circuit which includes anormally open switch SW3. Switch SW3 is also mounted in the stenographicmachine and is operated in response to the operation of the shift leverwhich causes certain of the keys to print a different character. RelayRY includes a plurality of contacts RYK which are wired with solenoidsS1 to effect a shift between two possible sets of interconnections ofthe solenoids with the capacitor controlling switches SW2. The twopossible sets of interconnections correspond to the two dilferent setsof characters which can be printed by the operation of the stenographicmachine keys by operating the shift lever. Since certain of the machinekeys print the same character in both shift positions, the correspondingrelay contacts for these keys are jumpered together.

In addition to the respective groups of solenoids, the relay outputcontacts are also connected to a common signal line L5 throughrespective isolating diodes D3. Line L5 is connected to the winding W4of a relay RY2 and also to a single hole punch solenoid EOL, which isemployed to mark the end of a line or tape section. The diodes D3 areelectrically oriented so that winding W4 and solenoid EOL are energizedwhen any of the solenoids S1 are energized by operation of therespective switches SW2. The diodes D3 prevent current from fiowing tothose of solenoids S1 which are not energized by operation of therespective switches SW2.

Relay RY2 includes D.P.D.T. contacts RYB. The normally closed contactsare wired to connect an energy storage capacitor C4 acrosselectromagnetic clutch 55. The normally open contacts are wired forconnecting capacitor C4 across the supply lines L3 and L4 to be charged.The value of capacitor C4 is chosen so that the energy stored thereinwill actuate clutch 55 for a predetermined interval sufficient toadvance the paper tape through the punch to place a new, unpunchedsection in position to be operated on by the punches.

The operation of this apparatus is as follows. When power is applied tothe cnotrol circuit, the capacitors C2 become charged. When acombination of the keys of the stenographic machine 11 are operated inconventional manner, the capacitors C2 corresponding to the operatedkeys are discharged through the respective solenoids S1 to actuate therespective punches. The punches are independently operable and thus maybe actuated simultaneously. The punch pins pierce the paper tape 17 inpatterns which represent the characters of the respective key being thenoperated. Thus the operation of a group of keys in combinationsimultaneously produces a section of punched tape containing thedigitally encoded representation of all the characters then beingprinted on the printed tape 13.

When any of the stenographic machine keys are operated, the solenoid EOLis energized simultaneously with those selected solenoids S1 whichproduced the encoded record. Solenoid EOL operates a single punch pinpositioned to one side of the main body of punches for the purpose ofmarking the location of each block or section of punch tape information.

Also simultaneously with the operation of any group of machine keys, therelays RY2 is energized. While relay RY2 is energized, capacitor C4 ischarged from supply lines L3 and L4. When relay RY2 becomes deenergized.capacitor C4 is discharged through the electromagnetically operatedclutch 55 thereby advancing the punched tape by a preselected distance.It can thus be seen that successive operations of the stenographicmachine keys in predetermined combinations will produce successivesections of a punched tape record in which each section includes thedigitally encoded representation of each character used in therespective line of the printed record. This punched tape can then bedecoded by conventional digital computing equipment to prepare a printedtranscription of the subject matter being recorded.

FIG. 7 illustrates the relationship between the printed tape recordproduced by the stenographic machine 11 and the punch-tape recordproduced by the punching apparatus 15. As noted previously, one fullsection of the punch-tape is produced for each row or line of theprinted tape record. The successive sections of the punch-tape areillustrated one on top of the other to more clearly show therelationship between the two record forms but it will be understoodthat, in fact, the successive sections are produced end-to-end so as toconstitute the length of the tape. Each section of tape includes in itsupper right hand corner a single perforation produced by the solenoidEOL, which single perforation is above the level of the rowsrepresenting the record characters. This single perforation indicatesthe edge of a section of tape containing the information representing asingle line of the printed tape record and does not represent a part ofthe record information and is not considered in the followingexplanation of the remaining perforation patterns.

The first printed line includes only the character T and thus the firstsection of the punch-tape is thus perforated in one vertical row only.the row corresponding in position ot the lateral position of thecharacter T within the printed tape record. The pattern of perforationspr0- duced in the punch-tape row represents the character T according tothe alphanumeric code conventionally employed for computer usage.

In the second printed line five characters appear and, in the section ofpunch-tape corresponding to this line five vertical rows are punched,the pattern in each row being distinctive and representing therespective character in the alphanumeric code mentioned previously. Thesuccessive lines and sections of punch-tape correspond similarly. It mayfor example be noted that, just as the letter B appears in foursuccessive lines in the printed tape record, the respective encodedpunch-tape pattern appears in the respective rows of the successivepunch-tape sections.

Since the patterns are distinctive. the punch-tape may be read byconventional digital computing equipment without further translation sothat a table retrieval propram may be accomplished quite quickly and theprinted record can be prepared as described previously with reference toFIG. 1.

In view of the above it will be seen that the several objects of theinvention are achieved and other advantageous results attained.

As various changes could be made in the above constructions withoutdeparting from the scope of the invention, it is intended that allmatter contained in the above description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitingsense.
